These brain teasers rely on your ability to recognize groups of common attributes. For each of these puzzles you'll need to figure out why the words or letters are grouped as they are. Sometimes you will be asked to pick the odd-one-out or to place a new word into the correct group.

You don't need to have studied Latin to know what common abbreviations, like those used in this teaser, stand for. It's a teaser to test your knowledge of common abbreviations, and finding what they have in common with each other. Obviously it's not going to be for everyone, but that doesn't mean it's not a valid teaser.

I thought it was great and quite easy actually. It was GLARINGLY OBVIOUS (to me anyway) that they were all Latin, and no, I have never taken Latin in school (by the time I was in school,, it was no longer offered, This said I have worked in both the medical and legal fields which rely heavily on Latin (though none of those is a common medical or legal term).
Don't worry about those who criticise, some people have little nice to say about the quizzes and teasers they take.

I had to think and observe for a whole minute, but then felt very satisfied exclaiming "etc!" Excellent teaser. (But where'd you get 'after death' from? Who says that? It doesn't even make sense Does it have to be part of the explanation?)

B.C. stands for "before Christ" and people who don't know that A.D. stands for "Anno Domini" think it means "after death".
This was a good quiz; thanks for posting! Once again, I love the comments as much as the quiz itself!
